Application filed June 17, 1919. Serial No. 304,329;

To all whom it may concern:

Be it known that I, "EDMUND H. LUNKEN,

' a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Vindow Shades, of which the followingis a full, clear, and exact description, reference being had to the drawings accompanying this specification. v

My invention relates to window shades,

I and more particularly to shades adapted to enclose the whole or' any partof the window either from the bottom or from the top of the window opening.

Among other uses to which a Window shade can be put, is to close theopening through the window from view, and yetpermit air to come in at the sides of the shade. Also, in many instances it is desirable to close the lower part of the window and perhaps some of the upper part, and yet permit light to come through the central portion thereof. In this latter way ventilation can be had through the central portionrof the window, persons are prevented from seeing 1 into the room, and the. light, from above is U My objects and advantages, as will be noted I accomplish bythat certain construc-- tion and'arrangement of parts to be'hereinafter more specifically pointed out and claimed, wherein, a fitting is provided for the window frame, the catches removed from the usual window shade rollers, and a modified bar inserted instead of the usual stiflening lath, in the free end of the shade, and

wherein also two shades are used, one mounted below the window opening and oneabove.

In the drawings,

Figure 1 is a front elevation ofa window showing the shade in use. 7 i

Figure 2 is a side elevation thereof.

Figure 3 is a detail perspective of one of the frame fittings.

Figure 4 is a detailside elevation of the curtain roller and its attachment.

Figure 5 is an elevation of the barv employed in the free end of the shades. I

Figure 6 is a perspective of a modified frame fitting.

The window, shown has a frame, with a sill 1, cap 2 and sides 3 and f. The curtain rollers 5 and 6 for the cap and sillrespec tively of the window frame, are of the usual pattern in wideuse at the present time, with the exception that I prefer to inhibit the action of the catchwhich holds the roller from exerting tension on the rollerfin'the' type of shade' Thus one usual typeof shade roller has a dogor catch 6*, which engages by gravity in a notch formed ,on the spindle ofthe roller. so arrange the notch on the roller splndle that it is held in a downward position, wherebythe dog will never form its gravlty engagement unless the curtain 1s re moved so as to be wound up, or the" spring I tightened on the spindle.

I The usual brackets for retaining the'roller in position are used for the upper and lower shades. Of these-the bracket 7 (Figure 4:). is shownretaining the roller 6at thesill' of the window frame, with; this roller equipped with the shade8. A' like fitting is at the upper end of the'window, near thecap thereof, having theroller 5 and the shade 9.

The usual stiffening lathpieces] are removed from the standard type of window shade, which is used with the rollers and the stiffening and retaining bar 10 inserted in the free, hemmed ends 8 and 9*, respectively,

of the two shades- These rods are made preferably stronger than the usual stiffening lath and have at their ends the extending pins 11, which protrude beyond theedges of the shades.

At the desired. number of points on e ach side of the window frame are mounted the" fiat double hooks 12, which may be of one piece, and have bases 13' to screw to the win dow frame. The hook portions shouldbe of considerable width so as to readily receive the pins on the stiffening bars in the ends of "the shades this width to be at least equalto double the width of one of the pins.

As so constructed the device operates as follows:The user lifts or pulls down the shades as desired, and places the pins on. the stiffening bars above or below the double hook fittings 12. Due to the spring being constant on the rollers, there will always be a tension exerted against the shades, tending to hold them against undue flapping, if the wind is free to enter the window due to the opening of the sash. For added ventilation, the hooks 12 may he provided with extended arms M and hooks l5, permitting an angled position of the shades (Figure 6).

Due to the width of the hooks, it makes no difference if the upper or lower shade is attached to any hook first since the pins can be pushed against the window frame thereby permitting-the pins on the other shade to find a seat on the opposite hook, The width of the shades is, of course, not enough to rub against the hooks, and as described, the standard shade and roller are used with the minimum amount of alteration.

, 1 do not desire to limit myself to the exact conformation of the hooks, or necessarily to the width thereof, neither do I wish to limit myself to the exact nature of the means employed to provide retaining pins at the free ends of the shades.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In a window shading device, the com bination with upper and lower shades for the cap and sill respectively of the window framaof fittings mounted at the sides ofthe fran'ie to simultaneously retain the free ends of both shade intermediate the window opening and adaptedito hold the shades in lapped relation.

neousjly-..

3. ln a window shading device, the combination with a lower and upper shade having extending portions at the free ends thereof, of a retaining device for said free ends located along the window frame, and Comprising a hooked element having hooks opening upwardly and downwardly, said hooks being of atleastsufiicient width to retain, side by side, two extending portions whereby each shade may be engaged in the hooks without displacement of the shade.

4. ln a window shading device the combination with a lower and upper shade under constant tension, of stiffening bars in the free ends of the shades, and retaining hooks niounted'at the sides of the window, said stiffening barshaving extending pins'at the sides of the shades and said hooks being open upwardly and downwardly, and the hook portions bothjupward and downward opening' being of at least twice the width of the extending pins.

, In a window shading device, the combi nation with upper and-lower shades for the cap and sill respectively of the window frame, same being mounted close to the frame, of fittings mounted at the sides of the frame intermediate the cap and sill. to retain;the free ends of both shades, said fittings being extending from the frame to retain the shades at a sloping position.

6. In a window shading device, the co nbination withupper and lower shades for the cap and sill-respectively of the window frame, same loeing mounted close to the fraiuaof lit-tings mounted at the sides of the frame intermediate the cap and sill toretain the free ends of both shades, said shades be ing under constant spring tension, said tittings being extended from the fran ie to re taintheshades a sloping position.
